GE Multilin L30 Line Current Differential System 5-1495 SETTINGS 5.6 GROUPED ELEMENTS5c) GROUND INSTANTANEOUS OVERCURRENT (ANSI 50G, IEC PIOC)PATH: SETTINGS GROUPED ELEMENTS SETTING GROUP 1(6) GROUND CURRENT GROUND IOC1(4)The ground instantaneous overcurrent element may be used as an instantaneous element with no intentional delay or as adefinite time element. The ground current input is the quantity measured by the ground input CT and is the fundamentalphasor magnitude.These elements measure the current that is connected to the ground channel of a CT/VT module. The conversionrange of a standard channel is from 0.02 to 46 times the CT rating.Figure 5–62: GROUND IOC1 SCHEME LOGIC GROUND IOC1GROUND IOC1FUNCTION: DisabledRange: Disabled, EnabledMESSAGE GROUND IOC1 SIGNALSOURCE: SRC 1Range: SRC 1, SRC 2MESSAGE GROUND IOC1PICKUP: 1.000 puRange: 0.000 to 30.000 pu in steps of 0.001MESSAGE GROUND IOC1 PICKUPDELAY: 0.00 sRange: 0.00 to 600.00 s in steps of 0.01MESSAGE GROUND IOC1 RESETDELAY: 0.00 sRange: 0.00 to 600.00 s in steps of 0.01MESSAGE GROUND IOC1 BLOCK:OffRange: FlexLogic™ operandMESSAGE GROUND IOC1TARGET: Self-resetRange: Self-reset, Latched, DisabledMESSAGE GROUND IOC1EVENTS: DisabledRange: Disabled, EnabledNOTESETTINGGROUND IOC1FUNCTION:Disabled = 0Enabled = 1SETTINGGROUND IOC1SOURCE:IGGROUND IOC1BLOCK:Off = 0FLEXLOGIC OPERANDSGROUND IOIC DPOGROUND IOC1 OPSETTINGSETTINGIG ≥ PICKUPGROUND IOC1PICKUP:RUNGROUND IOC1 PICKUPDELAY:SETTINGSGROUND IOC1 RESETDELAY:tPKPtRST827037A4.VSDANDGROUND IOC1 PKP
